How to read this index
This page lists notable items with plain-language effects. Numbers are described, not quoted, until we verify them against the game’s own data.
Use it to scan what an item might do before a run. Treat every figure here as a description, not a promise.
Items stack, so a single copy is often only the start. The stacking shape is noted where it changes a decision.

Using the index in a run
Check the tier before you chase a copy. Boss items and lunar items come from their own sources, not from normal chests.
For lunar items, read the downside in the same row. A strong upside with a matching cost changes how you play the whole run.
Why some rows are vague on purpose
Every number here is described rather than quoted. A precise stat line needs the game’s own data, and we publish those only after a data pass.
The behaviour is what matters for a decision. Whether an item triggers on hit, on kill, or over time decides how you use it.
